cPanel Migrate EasyApache 3 to EA4

Issue: cPanel is ending support for EA3 in January 2018. Servers that use FastCGI are not yet natively supported in EA4.

Update: This is an old post. All cPanel now comes standard with EA4. This post left live for posterity only.

Reguired:

• Apache-FastCGI
• Ability to install and use Apache DSO
• PHP-MailHeaders
• Apache-Fileprotect
• Apache Mod Cloudflare
• Apache Access

Solution:

Apache-FastCGI – To install mod_fcgid, enable the “Experimental Repository”

yum install ea4-experimental

To install FastCGI:

yum install ea-apache24-mod_fcgid

Or remove it (if removal is ever required):

yum remove ea-apache24-mod_fcgid

FastCGI and EA4 Caveats:

• You cannot use the FastCGI daemon (FCGId) with MultiPHP.
• mod_fcgid Apache moduleis recommended for advanced system administrators who understand how to modify the performance of the mod_fcgid Apache module.

Apache DSO – You can install the DSO PHP package in the PHP Extensions section of WHM’s EasyApache 4 interface via WHM >> Home >> Software >> EasyApache 4

PHP-MailHeaders – This functionality is included by default with PHP in EasyApache 4. You can test this by sending a test email via a PHP script and noticing the “X-PHP-Script” entry in the message header.

Apache-Fileprotect – File Protect is enabled via the “Enable File Protect” option under the “Security” tab in “WHM >> Tweak Settings” on systems using EasyApache 4.

Apache Mod Cloudflare – GitHub’s latest installer includes support for EasyApache 4:
https://github.com/cloudflare/mod_cloudflare

Apache Access – In the case of Mod_Access, it’s deprecated in Apache 2.4. Thus, it’s not included with EasyApache 4. Instead, the following modules are compiled with Apache by default:
mod_access_compat.so
mod_auth_basic.so
mod_authn_core.so
mod_authn_file.so
mod_authz_core.so
mod_authz_groupfile.so
mod_authz_host.so
mod_authz_user.so
